Problems of submersible sewage pump:
Submersible sewage pump for the vertical layout, pump and motor axis, which makes the weight of rotating parts and hydraulic impeller exposed to the same direction; secondly, the sewage pump is used in the liquid, the sewage transport medium containing impurities, silt and other substances; third, a centrifugal submersible sewage pump is in. When it is running, the power is always increased with increasing flow, when the flow exceeds the design flow and reaches a certain value, the motor will be due to overload and burn.
All of the above problems will affect the service life of submersible sewage pump in different degree.
Development direction of submersible sewage pump :
In view of the problem of submersible sewage pump, some domestic manufacturers to focus on the development of pump protection system: automatic alarm or cut off the power supply when the pump running. While this approach can play a certain effect, but this protection is necessary, but this is not the fundamental way to solve the problem, we need to focus on improving the performance of the pump, to fundamentally solve the problem.
In addition, the development of the product should also take full account of environmental issues, so that products are more energy-efficient R & D, environmental protection.
To sum up, the future need to solve the problem of submersible sewage pump is to improve the reliability of the use, can adapt to a variety of working environment, optimize its structural design, to further improve the performance of submersible sewage pump.
